SPECIFICATION forming part of Letters Patent No. 234,925, dated November30, 1880. Application filed March 23, 1880. (ModeL) To all whom it mayconcern:

Be it known that l, WILLIAn H. PATTER- SON, of Cleveland, in the countyof Cuyahoga and State of Ohio, have invented certain new and usefulImprovements in Tube-Machines; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it pertains to make and useit, reference being had to the accompanying d rawings, which form partof this specification.

In the drawings, Figure 1 is an isometric view of a device embodying myinvention. Fig. 2 is a transverse vertical sectional view of the samethrough the first guides, showing, in crosssection, the former, thefirst guides, and the web of paper from which the tube is made. Fig. 3is a sectional view of the same device through the second guides,showing, in cross-section, the former, the second guides, and the web ofpaper as it passes from the second guides. Fig. 4 is a view, incross-section of the plicated tube when complete, with the exception ofbeing united with paste. Fig. 5 is a view, in cross-section, of mydevice through the finger-E. showing the former,'the finger E, its armE, and the web of paper C.

In the said drawings, A represents a frame accommodating and supportingthe operative parts of my device.

B represents the former, preferably made of sheet metal or other thinfirm material. This former is suspended over the bed of the machine inany suitable manner.

D D represent the first two guides, between which and the former B theweb of paper passes.

E represents a removable finger supported and suspended over and withinthe web of paper by the arm E. This arm E also preferably madeadjustable.

F and F are guides substantially inclosing the former, and through whichthe web passes, and by which the final fold is made.

The guides D D and F F are preferably made of sheet metal.

The operation of my device is as follows: Paper is preferably taken froma roll of any length and of suitable width to make the sized bagdesired. It is passed under the former B and over the former and betweenthe same and the guidesDD. As it is drawn between the guides D D and theformer B the first folds a a, Fig. 4, are made. The web is then drawnover the finger E, which creases the web at the points I) b, and at thesame time spreads the web of paper, thereby causing the same to becreased at the points 0 c by the guides D D as it is being drawn overthem. These points a 0 thus creased subsequently become the middle foldof the plicated tube. The web of paper now passes under the last guidesF and F, when the form of the tube is completed, as shown in Fig.3.ltnow is taken. to the feed-rolls, when the tube is completed. Paste maybe applied to the tube at any point between the roll from which it istaken and the feed-rolls.

What I claim is 1. In a tube-machine, the combination, with singleformer B and guides l), which press the first side folds upon saidformer, of guide E, which operates upon the interior side of the web andpresses the second side folds directly upon the first side folds,substantially as set forth.

2. In atube-machine, the combination, with single former B and guide E,which operates upon the interior side of the web and forms the secondside folds, of guides E, which press the third side folds directly uponthe second side folds, substantially as set forth.

3. In a tube-machine, the combination, with single former B and guidesD, which press the first side folds upon said former, of guide E, whichoperates upon the interior side of the web and presses the second sidefolds directly upon the first side folds, and guides F, which press thethird side folds directly upon the second side folds, substantially asset forth.

In testimony whereofI have signed my name to this specification in thepresence of two subscribing witnesses.

WILLIAM H. PATTERSON.
